A field study was conducted to evaluate the accuracy of the Standardized Field Sobriety Test (SFST) battery to assist officers in making arrest decisions at blood alcohol concentrations (BACs) below 0.10%.
The SFST Battery was validated at 0.10% BAC in 1981, but since then many states have reduced statutory limits for driving while intoxicated to 0.08% BAC.
During routine patrols, participating officers followed study procedures in administering SFSTs, scoring results, making arrest/no arrest decisions, and completing a data collection form for each of the 297 motorists evaluated during the study period. The officers' final step in each case was the administration of an evidentiary breath alcohol test.
Overall, officers' decisions were correct in more than 91% of the cases at the 0.08% BAC level. Cohen's kappa tests found all officers' scores to be within the categories of "substantial" and "near perfect" agreement, indicating low variance among the officers and a high degree of interrater reliability.
The results of this study provide evidence of the validity of the SFST Battery as an accurate and reliable decision aid for discriminating between BACs above and below 0.08%.
The SFST Battery presently is used by law enforcement officers throughout the United States to help make roadside arrest decisions for impaired driving.
开展一项现场研究，以评估标准化现场清醒度测试（SFST）组合测试在协助警官对血液酒精浓度（BAC）低于0.10%的情况做出逮捕决定时的准确性。
SFST组合测试于1981年在BAC为0.10%时得到验证，但自那时起，许多州已将醉酒驾驶的法定限值降至BAC 0.08%。
在常规巡逻期间，参与的警官遵循研究程序来实施SFST、对结果评分、做出逮捕/不逮捕决定，并为研究期间评估的297名驾车者中的每一位填写一份数据收集表。警官在每个案件中的最后一步是进行呼气酒精含量证据检测。
总体而言，在BAC为0.08%的水平下，警官的决定在超过91%的案件中是正确的。科恩kappa检验发现所有警官的评分都在“高度一致”和“近乎完美一致”的类别内，表明警官之间的差异较小且评分者间信度较高。
本研究结果为SFST组合测试作为区分BAC高于和低于0.08%的准确且可靠的决策辅助工具的有效性提供了证据。
目前，美国各地的执法人员都使用SFST组合测试来协助做出路边对酒驾者的逮捕决定。
